>We now have enough data to know that the track record of companies that go through multiple accelerators is much worse than companies that just do YC.

Unfair or not, their job is to choose companies that will benefit YC. If the data shows that companies with property X do worse, asking them to lose money because they want to be "fair" is not a reasonable request.

Of course, individual cases might be an exception. And YC does accept, but with higher expectations/requirements.
